RESUMEN
INTRODUCTION: The presence of an epicardial connection (EC) decreases the success rate of pulmonary vein isolation (PVI); however, the effect of designing isolation lines has not been evaluated. We sought to clarify the effects of designing an anterior line for right-sided PVI considering the presence and location of the EC. METHODS: Seventy-four consecutive patients who underwent initial catheter ablation for atrial fibrillation were retrospectively included in this study. The presence of the EC was determined by the left atrial (LA) activation map during right atrial pacing, and patients were divided into EC-positive (n = 23, 31%) and EC-negative (n = 51, 69%) groups. EC-positive patients were further subdivided based on the EC location: on-the-line group, (EC on the PVI line, n = 11); inside-line group (EC on the pulmonary vein [PV] side, n = 10); and outside-line group (EC on the LA side, n = 2). The PVI parameters were compared among the three groups. RESULTS: The success rates of the first-pass isolation were comparable between the EC-negative and EC-positive groups (70.6% vs. 60.9%, ns), but the success rate was significantly higher in the on-the-line group than in the inside-line group (91% vs. 20%, p = 0.002). First-pass isolation was successful in both patients in the outside-line group. Additional carina ablation was required only in the inside-line group. CONCLUSIONS: The association between the EC site and the right-sided PV anterior isolation line affected the success rate of first-pass isolation. For successful right-sided PVI, it is important to consider the EC site when designing the PVI line.

BACKGROUND: There is a scarcity of studies comparing the clinical outcomes after percutaneous coronary intervention (PCI) for women and men stratified by the presentation of acute coronary syndromes (ACS) or stable coronary artery disease (CAD).MethodsâandâResults: The study population included 26,316 patients who underwent PCI (ACS: n=11,119, stable CAD: n=15,197) from the CREDO-Kyoto PCI/CABG registry Cohort-2 and Cohort-3. The primary outcome was all-cause death. Among patients with ACS, women as compared with men were much older. Among patients with stable CAD, women were also older than men, but with smaller difference. The cumulative 5-year incidence of all-cause death was significantly higher in women than in men in the ACS group (26.2% and 17.9%, log rank P<0.001). In contrast, it was significantly lower in women than in men in the stable CAD group (14.2% and 15.8%, log rank P=0.005). After adjusting confounders, women as compared with men were associated with significantly lower long-term mortality risk with stable CAD but not with ACS (hazard ratio [HR]: 0.75, 95% confidence interval [CI]: 0.69-0.82, P<0.001, and HR: 0.92, 95% CI: 0.84-1.01, P=0.07, respectively). There was a significant interaction between the clinical presentation and the mortality risk of women relative to men (interaction P=0.002). CONCLUSIONS: Compared with men, women had significantly lower adjusted mortality risk after PCI among patients with stable CAD, but not among those with ACS.

BACKGROUND: Outcomes of cryoballoon ablation for persistent atrial fibrillation (AF) are unclear, especially in Japanese patients, so the effectiveness and safety of cryoballoon ablation in clinical practice were retrospectively compared with those of contact force-sensing radiofrequency (CFRF) ablation including the high-power protocol.MethodsâandâResults:Consecutive patients with persistent AF were reviewed, and 253 and 265 patients who underwent cryoballoon and CFRF ablation, respectively, were enrolled. The primary endpoint was atrial arrhythmia recurrence. The secondary endpoints were periprocedural complications and repeat ablation. The rate of additional left atrial (LA) ablation after pulmonary vein isolation (PVI) was similar between groups (68.8% cryoballoon vs. 74.0% CFRF, P=0.19). Freedom from atrial arrhythmia recurrence was comparable between groups over a follow-up of 25.5±12.5 months (72.3% cryoballoon vs. 69.8% CFRF; adjusted hazard ratio (HR) 0.85, 95% confidence interval (CI) 0.59-1.21, P=0.36). Outcomes were similar in the subgroups of PVI alone and PVI plus additional LA ablation. LA posterior wall isolation, absence of defragmentation, and low creatine clearance, but not catheter selection, were associated with the primary endpoint. Periprocedural complications (adjusted HR 0.73, 95% CI 0.34-1.54, P=0.41) and repeat ablation (adjusted HR 1.11, 95% CI 0.71-1.74, P=0.64) were similar for both procedures. CONCLUSIONS: Cryoballoon ablation for persistent AF in Japanese clinical practice had acceptable outcomes comparable to those of advanced CFRF ablation.

BACKGROUND: Optimal intensity is unclear for P2Y12receptor blocker therapy after percutaneous coronary intervention (PCI) in real-world clinical practice.MethodsâandâResults: From the CREDO-Kyoto Registry, the current study population consisted of 25,419 patients (Cohort-2: n=12,161 and Cohort-3: n=13,258) who underwent their first PCI. P2Y12receptor blocker therapies were reduced dose of ticlopidine (200 mg/day), and global dose of clopidogrel (75 mg/day) in 87.7% and 94.8% of patients in Cohort-2 and Cohort-3, respectively. Cumulative 3-year incidence of GUSTO moderate/severe bleeding was significantly higher in Cohort-3 than in Cohort-2 (12.1% and 9.0%, P<0.0001). After adjusting 17 demographic factors and 9 management factors potentially related to the bleeding events other than the type of P2Y12receptor blocker, the higher bleeding risk in Cohort-3 relative to Cohort-2 remained significant (hazard ratio (HR): 1.52 95% confidence interval (CI) 1.37-1.68, P<0.0001). Cohort-3 compared with Cohort-2 was not associated with lower adjusted risk for myocardial infarction/ischemic stroke (HR: 0.96, 95% CI: 0.87-1.06, P=0.44). CONCLUSIONS: In this historical comparative study, Cohort-3 compared with Cohort-2 was associated with excess bleeding risk, which might be at least partly explained by the difference in P2Y12receptor blockers.

Background Recent imaging techniques show that patients with aortic intramural hematoma (IMH) have various sizes of focal intimal disruptions (FIDs) that may affect clinical outcomes. Purpose To evaluate the relationship between size of FIDs detected at multidetector CT and disease progression in patients with type B IMH. Materials and Methods This retrospective study analyzed consecutive patients with type B IMH who underwent multidetector CT at admission within 24 hours after symptom onset from January 2011 to March 2017. FID was defined as a focal contrast material-filled pouch projecting outside of the aorta lumen with a communicating orifice greater than 3 mm. Large FID was defined as an FID of at least 10 mm in length and width and at least 5 mm in depth. Aorta-related events were defined as a composite of aortic rupture, surgical or endovascular aortic repair, progressive aortic enlargement, and development of aortic dissection. Results Seventy-six patients (mean age, 72 years ± 11 [standard deviation]; 54 men) were evaluated. Fifty patients (66%; 50 of 76) had 91 FIDs. Twenty-eight patients had large FIDs and 22 patients had small FIDs. Aorta-related events occurred in 15 of 28 patients with large FIDs, two of 22 patients with small FIDs, and four of 26 patients with no FID. Patients with large FIDs showed lower aorta-related event-free survival rates than did patients with small FIDs or no FID (small FIDS, 63% ± 10 vs 90% ± 7 at 3 years, respectively [P = .001]; and no FIDS, 63% ± 10 vs 84% ± 7 at 3 years, respectively [P = .005]). Multivariable analysis showed that a maximum aortic diameter of at least 40 mm (hazard ratio, 4.8; 95% CI: 1.8, 12.6; P = .001) and large FID (hazard ratio, 3.2; 95% CI: 1.1, 8.9; P = .03) were the independent predictors of aorta-related events. Conclusion A large portion of patients with B-intramural hematoma (IMH) had focal intimal disruption (FID) detected at CT at admission. Large FIDs were associated with disease progression of IMH. © RSNA, 2021 See also the editorial by Raptis and Braverman in this issue. Online supplemental material is available for this article.

BACKGROUND: Data evaluating the effects of acute coronary syndrome (ACS) relative to stable coronary artery disease (CAD) on bleeding risk after percutaneous coronary intervention (PCI) are scarce.MethodsâandâResults:From the CREDO-Kyoto Registry Cohort-3, 13,258 patients undergoing first PCI (5,521 ACS; 7,737 stable CAD) were identified. Patients were further stratified according to ACS presentation and Academic Research Consortium High Bleeding Risk (HBR): ACS/HBR: n=2,502; ACS/no-HBR: n=3,019; stable CAD/HBR: n=3,905; and stable CAD/no-HBR: n=3,832. The primary bleeding endpoint was Bleeding Academic Research Consortium 3/5 bleeding, whereas the primary ischemic endpoint was myocardial infarction (MI)/ischemic stroke. Compared with stable CAD, ACS was associated with a significantly higher adjusted risk for bleeding (hazard ratio [HR] 1.85; 95% confidence interval [CI] 1.68-2.03; P<0.0001), with a markedly higher risk within 30 days (HR 4.24; 95% CI 3.56-5.06; P<0.0001). Compared with the stable CAD/no-HBR group, the ACS/HBR, no-ACS/HBR, and ACS/no-HBR groups were associated with significantly higher adjusted risks for bleeding, with HRs of 3.05 (95% CI 2.64-3.54; P<0.0001), 1.89 (95% CI 1.66-2.15; P<0.0001), and 1.69 (95% CI 1.45-1.98; P<0.0001), respectively. There was no excess adjusted risk of the ACS relative to stable CAD group for MI/ischemic stroke (HR 1.07; 95% CI 0.94-1.22; P=0.33). CONCLUSIONS: Bleeding risk after PCI depended on both ACS presentation and HBR, with a significant effect of ACS within 30 days.

BACKGROUND: The prevalence of and expected bleeding event rate in patients with the Japanese version of high bleeding risk (J-HBR) criteria are currently unknown in real-world percutaneous coronary intervention (PCI) practice.MethodsâandâResults:We applied the J-HBR criteria in the multicenter CREDO-Kyoto registry cohort-3 that enrolled 13,258 consecutive patients who underwent first PCI. The J-HBR criteria included Japanese-specific major criteria such as heart failure, low body weight, peripheral artery disease and frailty in addition to the Academic Research Consortium (ARC)-HBR criteria. There were 8,496 patients with J-HBR, and 4,762 patients without J-HBR. The J-HBR criteria identified a greater proportion of patients with HBR than did ARC-HBR (64% and 48%, respectively). Cumulative incidence of the Bleeding Academic Research Consortium (BARC) type 3 or 5 bleeding was significantly higher in the J-HBR group than in the no-HBR group (14.0% vs. 4.1% at 1 year; 23.1% vs. 8.4% at 5 years, P<0.0001). Cumulative 5-year incidence of BARC 3/5 bleeding was 25.1% in patients with ARC-HBR, and 23.1% in patients with J-HBR. Cumulative incidence of myocardial infarction or ischemic stroke was also significantly higher in the J-HBR group than in the no-HBR group (6.9% vs. 3.6% at 1 year; 13.2% vs. 7.1% at 5 years, P<0.0001). CONCLUSIONS: The J-HBR criteria successfully identified those patients with very high bleeding risk after PCI, who represented 64% of patients in this all-comers registry.

BACKGROUND: The effect of diabetes mellitus (DM) status on the long-term risk for heart failure (HF) in patients undergoing coronary revascularization has not been adequately evaluated.MethodsâandâResults:In this study, 15,231 patients who underwent coronary revascularization in the CREDO-Kyoto Registry Cohort-2 were divided into 2 groups according to DM status (DM group: n=5,999; Non-DM group: n=9,232). The DM group was further divided into 2 groups according to insulin treatment (insulin-treated DM [ITDM]: n=1,353; non-insulin-treated DM [NITDM]: n=4,646). The primary outcome measure was HF hospitalization. The cumulative 5-year incidence of HF hospitalization was significantly higher in the DM than non-DM group (11.0% vs. 6.6%, respectively; log-rank P<0.0001), and in the ITDM than NITDM group (14.6% vs. 10.0%, respectively; log-rank P<0.0001). After adjusting for confounders, the increased risk of HF hospitalization with DM relative to non-DM remained significant (hazard ratio [HR] 1.47, 95% confidence interval [CI] 1.30-1.67, P<0.0001), whereas the risk associated with ITDM relative to NITDM was not significant (HR 1.17, 95% CI 0.96-1.43, P=0.12). CONCLUSIONS: The adjusted long-term risk for HF hospitalization after coronary revascularization was significantly higher in DM than non-DM patients, regardless of revascularization strategy, but did not differ between ITDM and NITDM patients.

BACKGROUND: There are no data comparing transcatheter aortic valve implantation (TAVI) with surgical aortic valve replacement (SAVR) outcomes in real clinical practice in Japan. METHODSâANDâRESULTS: We combined 2 independent registries, the K-TAVI Registry (a 6-center prospective registry of consecutive patients who underwent TAVI) and the CURRENT AS Registry (a large, 27-center registry of 3,815 consecutive patients with severe aortic stenosis [AS]). In the K-TAVI Registry, 338 patients underwent TAVI with SAPIEN XT balloon-expandable valves from October 2013 to January 2016, whereas in the CURRENT AS Registry 237 patients with severe AS underwent SAVR from January 2003 to December 2011. Propensity score matching was conducted, with final cohort comprising 306 patients. The cumulative 2-year incidence of all-cause death and heart failure (HF) hospitalization did not differ significantly between the TAVI and SAVR groups (13.7% vs. 12.4% [P=0.81] and 7.9% vs 3.9% [P=0.13], respectively). After adjusting for residual confounders, there were no significant differences between the TAVI and SAVR groups in the risk for all-cause death (hazard ratio [HR] 0.74; 95% confidence interval [CI] 0.35-1.58; P=0.43) or HF hospitalization (HR 1.27; 95% CI 0.40-4.59; P=0.69). CONCLUSIONS: These findings from 2 independent Japanese registries suggest that the 2-year risk of all-cause mortality and HF does not differ significantly between TAVI and SAVR groups in real-world practice in Japan.

An 85-year-old woman with severe aortic stenosis (AS) and coronary artery disease (CAD) was admitted with heart failure 3 times. Direct aorta transcatheter aortic valve replacement( DA-TAVR) and off-pump coronary artery bypass grafting (OPCAB) were performed after percutaneous coronary intervention (PCI), and she was discharged without postoperative complication. Surgical aortic valve replacement and coronary artery bypass grafting(CABG) are recommended for a patient with AS and CAD. Recently, PCI or CABG with transcatheter aortic valve replacement(TAVR) has been reported, although there is no standard treatment for concomitant CAD in patients who undergo TAVR. DA-TAVR and OPCAB after PCI is considered as a reasonable treatment for high-risk patients.

Several studies have reported that the left ventricular (LV) lead implant success rate ranges between 88.0% and 92.4%. Coronary venous anatomy differs among patients thus, necessitating multiple types of leads. To date, the implant success rate among Japanese patients utilizing a pre-specified family LV leads (including bipolar and quadripolar) is not well known. The Attain Success Japan Study enrolled patients indicated for a de novo or an upgrade cardiac resynchronization therapy implant. Patients were followed for 3 months, and the implant success rates with Medtronic Attain family LV leads as well as the incidence of complications related to the LV lead were evaluated.Three hundred 53 patients were enrolled from 29 sites in Japan; 346 patients had LV lead implant attempts. The LV lead was successfully implanted in 336 patients (97.1%). Bipolar and quadripolar LV lead implants were successful in 97.2% and 99.2% of patients, respectively (P = 0.43). Four complications (1.2%) related to the LV leads were reported; all of which occurred in patients receiving bipolar LV leads. The quadripolar LV leads were more frequently implanted in the apical segment compared with bipolar leads (21.6% versus 3.8%, P < 0.01). This study demonstrated a high implant success rate and a low LV lead-related complication rate, regardless of bipolar, or quadripolar in a Japanese cohort of patients.

BACKGROUND: Very limited data exist on the outcomes of transcatheter aortic valve implantation (TAVI) since Japanese marketing approval of the first TAVI device.MethodsâandâResults:The Kyoto University-related hospital Transcatheter Aortic Valve Implantation (K-TAVI) registry includes prospectively collected data from 6 participating hospitals in Japan. We included 302 patients with severe aortic stenosis who underwent TAVI using the SAPIEN XT balloon-expandable valve via transfemoral (TF; n=203, 67%) or transapical (TA; n=99, 33%) approach between October 2013 and September 2015. Device success rate, based on the Valve Academic Research Consortium-2 criteria, was very high in the TF (97.0%) and TA (99.0%) groups. The 30-day mortality rates were 1.5% and 1.0% in the TF and TA groups, respectively. Major complications included stroke (transient or persistent: 2.3%), annulus rupture (1.0%), coronary intervention (1.0%), major vascular complications (1.7%), and permanent pacemaker implantation (5.4%). The procedure times of the post-proctoring period (n=210) were decreased compared with those of the proctoring period (n=89) without affecting the clinical outcomes. The survival rates at 6 and 12 months were 96.9% and 92.5% in the TF group, and 93.9% and 91.8% in the TA group, respectively. CONCLUSIONS: The K-TAVI registry data revealed that the early outcomes of TAVI using the SAPIEN XT were favorable in real-world Japanese patients.

Acute coronary occlusion just after transcatheter aortic valve implantation (TAVI) is a rare but fatal complication, with an incidence of less than 1% but a 30-day mortality rate of up to 50%. The most likely mechanism of acute coronary occlusion following TAVI is the obstruction by the native aortic valve leaflet. However, acute coronary occlusion due to embolus has been rarely reported, and we herein report the case. An 80-year-old woman with severe aortic stenosis and chronic myelogenous leukemia (CML) underwent transfemoral TAVI with a 23-mm balloon-expandable valve. Just before leaving an operation room about 30 minutes after the TAVI procedure, she went into cardiopulmonary arrest. Emergent coronary angiography showed the occlusion of the middle to the distal left main coronary artery with a large embolus. Percutaneous coronary intervention (PCI) was immediately performed, and a drug-eluting stent was eventually placed to improve good coronary flow. She was finally discharged on foot without any other complications and was doing well one year after TAVI with normal left ventricular systolic function and no in-stent restenosis. Considering the transthoracic echocardiography before TAVI and the intravascular ultrasound findings during PCI, it was most likely thought to be caused by the embolus of the degenerated aortic valve tissue. In conclusion, although acute coronary occlusion by embolization following the TAVI procedure is exceedingly rare, we could successfully rescue the patient with immediate PCI.
RESUMEN
BACKGROUND: The Heart Failure Association Pretest assessment, echocardiography and natriuretic peptide, functional testing and final aetiology (HFA-PEFF) score has been developed for diagnosing heart failure with preserved ejection fraction (HFpEF), which is frequently associated with atrial fibrillation (AF). We aimed to investigate whether preprocedural HFA-PEFF score could be used to predict clinical outcomes in patients with AF who underwent catheter ablation (CA). METHODS: Overall, 1679 patients with AF who underwent primary CA (71±10 years, 1218 males (72.5%), median follow-up duration 3.3 years) from July 2011 to December 2019 were included in this retrospective study. HFpEF was defined as an HFA-PEFF score ≥5. The primary study outcome was 5-year major adverse cardiovascular and cerebrovascular events (MACCE), which is a composite of all-cause death, hospitalisation for heart failure (HF) and hospitalisation for stroke. RESULTS: The prevalence of HFpEF was 32.3%, but only 7.7% were diagnosed with HF at the time of CHADS2 scoring. Five-year MACCE occurred in 77 patients (4.6%). The cumulative 5-year incidence of MACCE was significantly higher in the HFpEF group than in the non-HFpEF group (11.2% vs 4.8% at 5 years, p<0.001). In the multivariable analysis, HFpEF by the HFA-PEFF score was associated with MACCE (adjusted HR 1.65, 95% CI 1.02 to 2.65, p=0.041). CONCLUSIONS: Early detection of HFpEF using the HFA-PEFF score may have clinical applications in guiding therapeutic decision-making and improving prognosis by preventing HF and stroke in patients with AF undergoing CA.

OBJECTIVE: There is a need for a robust tool to stratify the patient's risk with COVID-19. We assessed the prognostic values of cardiac biomarkers for COVID-19 patients. METHODS: This is a single-centre retrospective cohort study. Consecutive laboratory-confirmed COVID-19 patients admitted to the Kobe City Medical Center General Hospital from July 2020 to September 2021 were included. We obtained cardiac biomarker values from electronic health records and institutional blood banks. We stratified patients with cardiac biomarkers as high-sensitive troponin I (hsTnI), N-terminal pro-B-type natriuretic peptide (NT-proBNP), creatine kinase (CK) and CK myocardial band (CK-MB), using the clinically relevant thresholds. Prespecified primary outcome measure was all-cause death. RESULTS: A total of 917 patients were included. hsTnI, NT-proBNP, CK and CK-MB were associated with the significantly higher cumulative 30-day incidence of all-cause death (hsTnI: <5.0 ng/L group; 4.3%, 5.0 ng/L-99%ile upper reference limit (URL) group; 8.8% and ≥99% ile URL group; 25.2%, p<0.001. NT-proBNP: <125 pg/mL group; 5.3%, 125-900 pg/mL group; 10.5% and ≥900 pg/mL group; 31.9%, p<0.001. CK: Asunto(s)

BACKGROUND: The impact of very low baseline levels of low-density lipoprotein cholesterol (LDL-C) on patients with coronary artery disease remains unclear. METHOD: We enrolled 39,439 patients of the pooled population from the CREDO-Kyoto registries Cohorts 1, 2, and 3. The study population consisted of 33,133 patients who had undergone their first coronary revascularization. We assessed the risk for mortality and cardiovascular events according to quintiles of the baseline LDL-C levels. RESULTS: Patients in the very low LDL-C quintile (<85â¯mg/dL) had more comorbidities than those in the other quintiles. Lower LDL-C levels were strongly associated with anemia, thrombocytopenia, and end-stage renal disease. The cumulative 4-year incidence of all-cause death increased as LDL-C levels decreased (very low: 19.4â¯%, low: 14.5â¯%, intermediate: 11.1â¯%, high: 10.0â¯%, and very high: 9.2â¯%; pâ¯<â¯0.001), which was driven by both the early and late events. After adjusting for baseline characteristics, the adjusted risks of the very low and low LDL-C quintiles relative to the intermediate LDL-C quintile remained significant for all-cause death (very low: HR 1.29, 95â¯% CI 1.16-1.44, pâ¯<â¯0.001; low: HR 1.15, 95â¯% CI 1.03-1.29, pâ¯=â¯0.01). The excess adjusted risks of the lowest LDL-C quintile relative to the intermediate LDL-C quintile were significant for clinical outcomes such as cardiovascular death (HR 1.17, 95â¯% CI 1.01-1.35), non-cardiovascular death (HR 1.35, 95â¯% CI 1.15-1.60), sudden death (HR 1.44, 95â¯% CI 1.01-2.06), and heart failure admission (HR 1.11 95â¯% CI 1.01-1.22), while there was no excess risk for the lowest LDL-C quintile relative to the intermediate LDL-C quintile for myocardial infarction and stroke. CONCLUSIONS: Lower baseline LDL-C levels were associated with more comorbidities and a significantly higher risk of death, regardless of cardiovascular or non-cardiovascular causes, in patients who underwent coronary revascularization.

BACKGROUND: It is controversial whether angiotensin-converting enzyme inhibitors (ACEI)/angiotensin receptor blockers (ARB) provide significant survival benefits in patients with coronary artery disease (CAD) but without myocardial infarction (MI). This study investigated whether the association of ACEI/ARB therapy with clinical outcome in patients undergoing percutaneous coronary intervention (PCI) was affected by history of MI. METHODS AND RESULTS: A total of 11,590 patients undergoing first PCI were divided into 2 groups: those with MI and those without MI. All-cause and cardiovascular mortality were compared between the patients with and without ACEI/ARB at discharge in each group. In patients with MI, significantly lower 3-year all-cause/cardiovascular mortality for patients with ACEI/ARB relative to those without ACEI/ARB was noted in the total patients (all-cause: 6.6% vs. 11.7%, P<0.0001; cardiovascular: 3.8% vs. 6.9%, P<0.0001) and in the 1,007 propensity score-matched pairs (all-cause: 8.2% vs. 11.3%, P=0.018; cardiovascular: 3.7% vs. 5.7%, P=0.014). In patients without MI, however, all-cause (5.2% vs. 5.6%, P=0.56) and cardiovascular (3.2% vs. 3.0%, P=0.23) mortality were similar regardless of whether ACEI/ARB were used or not; and similarly in the 2,061 propensity score-matched pairs (all-cause: 4.1% vs. 5.4%, P=0.33; cardiovascular: 1.4% vs. 2.1%, P=0.30). CONCLUSIONS: Use of ACEI/ARB at hospital discharge was associated with lower all-cause/cardiovascular mortality in revascularized CAD patients with MI, but not in those without MI.

BACKGROUND: Limited data are available for sex-based differences in Japanese patients with acute myocardial infarction (AMI) undergoing primary percutaneous coronary intervention (PCI). METHODS AND RESULTS: The study patients comprised 1,197 women and 3,182 men who underwent primary PCI for AMI in 2005-2007. Compared with the men, the women were significantly older, and had significantly longer onset-to-balloon time and lower rate of follow-up coronary angiography. In-hospital mortality was higher among women than men (8.7% vs. 4.9%, P<0.001). Although the cumulative incidence of all-cause death at 3 years was also higher for women (17.7% vs. 10.7%, P<0.001), the adjusted risk for all-cause death was comparable [hazard ratio (HR, women vs. men)=0.94, 95% confidence interval (CI): 0.71-1.24, P=0.66]. The incidence (12.1% vs. 12.4%, P=0.77) and the adjusted risk (HR=0.99, 95% CI 0.78-1.24, P=0.92) for any clinically-driven coronary revascularization were both comparable. However, regarding any non-clinically-driven coronary revascularization, the incidence (19.6% vs. 27.8%, P<0.001) and the adjusted risk (HR=0.79, 95% CI 0.65-0.95, P=0.012) were both lower in women relative to men. CONCLUSIONS: In current Japanese clinical practice for AMI, onset-to-balloon time was significantly longer in women than in men. Female sex was associated with lower follow-up coronary angiography rate and lower incidence of any non-clinically-driven coronary revascularization, whereas the incidence of any clinically-driven coronary revascularization was comparable between the sexes.

Background The natural history and optimal interventional timing in patients with isolated severe tricuspid regurgitation (TR) have not been well studied. This study aimed to investigate long-term clinical outcomes and risk factors associated with poor prognosis in patients with isolated severe TR. Methods and Results Consecutive transthoracic echocardiographic examinations in 2877 patients with isolated severe TR were retrospectively reviewed. Patients with significant left-sided valve disease or repeated examinations were excluded. Primary outcome was defined as a composite of all-cause death and hospitalization for heart failure. Among the 613 enrolled patients (mean age, 74±13 years; men, 38%), 141 died, and 62 were hospitalized for heart failure during the median follow-up period of 26.5 (interquartile range, 6.0-57.9) months. The 5-year event-free rate was 60.1%. TR pressure gradient (adjusted hazard ratio [HR], 1.03 [95% CI, 1.01-1.04]), blood urea nitrogen (adjusted HR, 1.02 [95% CI, 1.01-1.04]), left atrial volume index (adjusted HR, 1.01 [95% CI, 1.002-1.02]), and serum albumin (adjusted HR, 0.56 [95% CI, 0.36-0.95]) were identified as independent predictors of adverse events. A risk model based on the 4 clinical factors that included pulmonary hypertension (TR pressure gradient >40 mm Hg), elevated blood urea nitrogen levels (>25 mg/dL), decreased albumin levels (<3.7 g/dL), and left atrial enlargement (left atrial volume index <34 mL/m2) revealed a graded increase in the risk of adverse events (P<0.001). Conclusions The prognosis of isolated severe TR is not always favorable. Careful attention should be paid to patients with concomitant risk factors, such as pulmonary hypertension, elevated blood urea nitrogen levels, decreased albumin levels, and left atrial enlargement.
